The OpenMotics Modules

General

Welcome to the Hardware Installation guide which will explain how to install and interconnect the OpenMotics modules This document describes the steps to install the OpenMotics hardware. All OpenMotics Modules are DIN rail mountable to ensure easy installation and wiring.

If you have some questions regarding which type of dimmer, heating valve/actuator or switch to use, please see the Additional Material page.

If you want to know if your heating system is compatible with OpenMotics, see the Heating Compatibility page.

The following space requirements apply for the fuse box dimensions (1 module width is approx 17.5mm):

  • Input, Dim Control, Temperature, CAN Control and power supply modules: 3 module widths
  • Gateway, Output and Energy modules: 6 module widths

Always reserve some additional space in the fuse box for future extensions.

Important remark: Your OpenMotics installation needs a 12VDC power supply. Please always use a separate dedicated power supply for your OpenMotics system with at least the following specifications:

  • 12VDC
  • 2 Amp (can be higher depending on the Number of modules being used)
  • CE approved

We advise to use the OpenMotics power supply to ensure CE compliance

Instructional videos

There are some instructional videos available on the OpenMotics YouTube page at youtube.com/OpenMotics

Wiring the bus

Wiring the bus and connecting the 12-24VDC power supply is simple and straight forward. The below example shows how a Starter Pack is connected. Please note that a different 12VDC power supply may be delivered but the principle remains the same.

Bus2.jpg

Connecting the Bus ...

In the example on the right only a Gateway and Input Module are used. This setup can be expanded with many more modules in any configuration.

Principles and cabling

  • The Gateway has 2 BUS connections:
    • BUS1: Connects all the OpenMotics Modules except the Energy modules (green wires on schematic 'Home Automation Data')
    • BUS2: Connects only the OpenMotics Energy modules (blue wires on schematic 'Power Measurement Data')
  • The A and B wire of each bus must be twisted and twisted pair must be used, especially when longer distances between the modules are required
  • The first and last module on both BUS1 and BUS2 must have a termination jumper set on the respective 'TR' pins; the other modules must have the termination jumper removed

Wiring

  1. Ask a certified electrician to make the mains connection (110-230VAC) to the 12VDC power supply. Make sure it is installed on a separate circuit breaker so maintenance can be easily performed.
  2. Make sure the power supply is switched off and all local safety precautions for working in the fuse box are met!
  3. Connect the '+12V' and the '-12V' of the power supply to the '+12V IN' and '-12V IN' connection on the Gateway module
  4. Connect the '-12V OUT' of the Gateway module to the '-12V IN' connections on all other modules (black wire on schematic)
    • When using multiple power supplies (e.g. multiple fuse boxes) always link the '-' connections (but not the '+' connections) of all power supplies in the installation!
    • Please use a wire with sufficient diameter (depending on the number of modules) that can support the peak currents (when switching relays for example)
  5. Connect the '+12V OUT' of the Gateway module to the '+12V IN' connections on all other modules (red wire on schematic)
  6. All modules except the Energy modules (if applicable):
    1. Connect the 'A' and 'B' wires of BUS1 on the Gateway module to the respective 'A' and 'B' BUS connections of all the modules on the bus (excluding the Energy modules): from the 1st to the 2nd module, 2nd to the 3rd, etc. Use only twisted pair!
    2. The first and last module on BUS1 need to be terminated. Place the jumper supplied with your Gateway module on the 'TR' jumper pins of the last module on BUS1. Typically the Gateway module is the first module on BUS1; if this is not the case: remove the 'TR1' jumper (factory set) from the Gateway module and move it to the 'TR' connection of the first module on BUS1. Ensure that no 'TR' jumpers are placed on any modules in between.
  7. Only the Energy modules (if applicable):
    1. Connect the 'A' and 'B' wires of BUS2 on the Gateway module to the respective 'A' and 'B' BUS connections of all the Energy modules on the bus: from the 1st to the 2nd module, 2nd to the 3rd, etc. Use only twisted pair!
    2. The first and last Energy module on BUS2 need to be terminated. Place the jumper supplied with your Gateway module on the 'TR' jumper pins of the last module on BUS2. Typically the Gateway module is the first module on BUS2; if this is not the case: remove the 'TR2' jumper (factory set) from the Gateway module and move it to the 'TR' connection of the first Energy module on BUS2. Ensure that no 'TR' jumpers are placed on any modules in between.
  8. Connect a standard Ethernet cable with RJ45 plugs (not supplied) to the Ethernet connector on the Gateway module and to your home network (note that DHCP must be enabled).
  9. Power on the 12VDC power supply and check the status of all installed modules to check if all front panel Power LEDs light up. If this is not the case: immediately switch off the power supply and look for possible causes.
    • Ensure that both the ‘Cloud’ and ‘VPN’ LEDs on the Gateway module front panel light up after a couple of minutes. This indicates a working internet connection to the OpenMotics Cloud.
  10. Power off the 12VDC power supply and connect all the inputs, outputs, sensors, etc. to your OpenMotics modules (see following chapters).
  11. After everything is installed, the system is powered on and the Gateway module is connected to the Internet the system can be set up using the OpenMotics Cloud (see following chapters)
    • Note that other configuration options (including offline installation) are also available.

In the example below a Gateway module, a Power module (since replaced by the Energy module) and an Input module are used. Of course, more modules can be connected on both BUS1 and BUS2, just make sure the jumper for each bus is set on the first and last module.

Module connections

Input module

The Input module is used to connect switches, push buttons or any other kind of input device (e.g. motion detectors, window/door contacts, pulse outputs for electricity/water/gas etc.) in a STAR topology. An Input module will detect any input as being triggered when the ground (labeled as '-' or 'GND') is applied to it. NO (Normally Open) as well as NC (Normally Closed) types of switches can be connected.

Typically, every switch in your building goes from the switch to the Input modules by using for example SVV, UTP or any other solid copper core cabling. The Input module uses STAR topology cabling. If BUS topology is preferred the CAN Control and micro CAN modules can be used instead.

Input.jpg

Notes:

  • Please not that every input has a pull up resistor to +5VDC. It’s important not to apply any voltages to the Input module except the '-' or 'GND' connection (when switched). In case of doubt (when using a motion detector for example), measure the output to make sure no voltages are applied so only devices with dry outputs should be used (for advanced users, open collector outputs can be used as well when properly designed). See PIR Motion Detector for more explanation.
  • The '-' or 'GND' connection on the Input module is used as the common wire (and is connected to ground), the second wire must be connected to one of the inputs ('INPUT 1-8'), see schematic.
  • Only connect 1 conductor per input connector! If multiple conductors need to be connected to the same input connector: use a wire connector
  • Switches of any brand that are “bounced potential free” can be used. The used push buttons should not contain any electronics (except perhaps LEDs)
  • The cables that connect the switches with the Input module can be any low voltage cable (alarm cable, UTP etc.) but solid copper is highly encouraged.
  • The connectors labeled 'NC' should not be used
  • Once an Input module has been added through the Cloud (or via maintenance mode), the orange status LED will flicker every few seconds to indicate that communication is working. This is normal behavior.
  • If you've some questions regarding which type of dimmer, heating valve/actuator or switch to use, please see the Additional Material page.
  • THE INPUT MODULE DOES NOT SUPPORT 230VAC! CONNECTING 230VAC TO THE INPUT MODULE MAY DESTROY YOUR INPUT MODULE AND IN SOME OCCASIONS YOUR COMPLETE INSTALLATION. ONLY APPLY THE OPENMOTICS GND (FROM THE 12VDC POWER SUPPLY) TO THE INPUT CONNECTIONS OF THE OPENMOTICS INPUT MODULE.


Connecting a motion sensor (or similar)

Different types of motion sensors can be connected to the OpenMotics system.

See PIR Motion Detector for more explanation.

Motion Sensor.JPG

CAN Control module

The OpenMotics system also supports switches that are connected in a BUS topology (as opposed to the Input module which uses STAR topology). For this, our CAN Control (fuse box) and micro CAN modules (throughout the building) are used. The CAN Control module will do the conversion between RS485 and CAN.

Install the CAN Control module(s) in your fuse box as described in the wiring the bus chapter. The micro CAN modules are installed throughout the building in a bus configuration and connect to the CAN Control module in the fuse box.

The CAN bus between the CAN Control and micro CAN module(s) must be terminated on the first and last module on the CAN bus. Place the jumper supplied with your CAN Control module on the 'TR' jumper pins of the last module on the CAN bus. Typically the CAN Control module is the first module on the CAN bus; if this is not the case: remove the 'TR2' jumper (factory set) from the CAN Control module and move it to the 'TR' connection of the first micro CAN module on the CAN bus. Ensure that no 'TR' jumpers are placed on any modules in between.

Connecting micro CAN modules

On the micro CAN module, switches and their feedback LEDs but also temperature and humidity sensors can be connected. Cable to use between CAN Control and the micro CANs: EIB (2x twisted pair, full copper, shielded, 0.8mm)

For more info on wiring color codes and connections of the micro CAN module, see the micro CAN Connections page.


CAN Micro2.jpg


Micro-CAN-Ext-Connections.png


Micro-CAN-Ext-Connections-Hum.png


Important Remark When adding or removing sensors, always disconnect the power before doing the wiring. A power reset is also needed when the hardware configuration of the sensors has changed. Please also note that a sensor of a micro CAN will only be added in the CAN Control when a button on the corresponding micro CAN is pressed. After this action, do an initialization of the CAN Control module to check if no new virtual modules have been added.

Connecting DALI equipment

The wiring of a DALI setup must be done as seen in the below schematic:

DALI.jpg

For normal operations, connector A and B (female and male DB9 connector) must be interconnected. When initialization of the DALI modules is needed, connector A must be connected to an USB-RS232 convertor which is connected to your PC with DALI software installed.

For more information regarding DALI equipment, see the DALI Installation Guide

Connecting the Output (Relay) Module

The Output Module comes equipped with 8 bistable 16A NO relays to control 8 electrical circuits or 4 roller shutters. Bistable relays are used to drastically lower the power consumption of the module. A standard relay consumes between 1W and 2W when it's activated while a bistable relay consumes no power (except when toggled). The relays are used to switch the AC mains (110-230VAC) as well as low voltage DC loads.

Output module for switching AC loads

Relay.jpg

Important Remark: The OpenMotics module has 2 output banks:

  • Bank1: Relay 1, 2, 3 and 4
  • Bank2: Relay 5, 6, 7 and 8

Bank1 has a common connection for its 4 relays as well as Bank2. In other words, there is no galvanic separation for the 4 relays within a bank since you've a common connection per bank. However, you've a full galvanic separation between the 2 banks.

For example, when relay 1 is used to switch 230VAC, relay 2, 3 and 4 can only be used to switch the mains as well because they share the same common wire.

Relay2.jpg

In the above example, we've also put the circuit breakers. The design of the circuit breakers depends on the electrical installation, the load and the local regulations. Many of our customers uses the below design where the 32A circuit breaker can also be a 40 of 64A circuit breaker which is used for all 16A circuit breakers. You can also use 1 circuit breaker per Output module when the total load of the 8 outputs is less than 16A. Also note that the 32A circuit breaker in the below design is used for multiple output modules as long as the 32A can bear the full load of all connected output modules and their load.

In case of any doubts, please ask the help of a certified electrician to assist you in the design and the connectivity.

Output module to drive actuators for heating/cooling

Below is an example design of a heating/cooling system with 13 actuators (valves) that works on 24VDC, a pump contact (when heating/cooling is required) and a dry contact that switches between cooling and heating.

HeatingCooling.jpg

Output module as Roller/shutter module

In its default mode the Output Module switches 8 electrical circuits, but the Module can also switch to Roller/Shutter mode to control 4 roller shutters:

Store.jpg

  • Each of the 4 AC connectors are coupled and used to control the up and down action of a roller shutter:
    • Roller Shutter couple 1: Output 1 & 2
    • Roller Shutter couple 2: Output 3 & 4
    • Roller Shutter couple 3: Output 5 & 6
    • Roller Shutter couple 4: Output 7 & 8
  • The 2 relays that control the 2 actions of each roller shutter cannot be switched on at the same time to prevent damage to the motor.
  • Enabling Roller Shutter Mode:
    • Before entering the "module discover start" command press the button next to the programming connector for 5 seconds
    • The LEDs of outputs 1, 3, 5, 7 (= 4 sets of roller shutters) will blink several times to indicate that the Module is now in Roller Shutter Mode
    • The Module's ID has now changed to "R"
  • Disabling Roller Shutter Mode:
    • To restore the Module to its (default) state, press the press the button next to the programming connector for 5 seconds before entering the "module discover start" command
    • All 8 output LEDs will blink several times to indicate that the Module is now in its default mode
    • The Module's ID has now changed to "O" (default)

Note: The orange status led will only flicker when communication is happening between the module and the Gateway. In normal circumstances, the status led will not flicker except when a port will change state.

Import Note for Roller/Shutter Mode: Before switching ON the AC power on the Roller/shutter modules, please make sure that the modules are in Roller/Shutter mode AND are initialised. Modules leaving the factory can have relays switched on resulting in damage of your equipment.

SO DO NOT CONNECT THE POWER OF YOUR ROLLER/SHUTTERS UNTILL YOU VERIFIED YOUR INSTALLATION, CONFIGURED YOUR OUTPUT MODULE(S) AS ROLLER/SHUTTER, INITIALISED YOUR MODULE(S), TESTED WITH A MULTI-METER BEFORE APPLYING ANY VOLTAGE TO YOUR ROLLER/SHUTTERS!

Connecting the Dim Control Module

The Dim Control Module has 8 analog 0-10V DC outputs that can be used to connect 0-10V dimmers of various brands as well as 0-10V DC heating valves.

Important Remark

In the market, you'll find 0-10V devices and 1-10V devices. The Openmotics Dim Control is only compatible with 0-10V devices.

Use of 110-230VAC dimmer

Dimmer.jpg

To connect dimmers to the Dim Control Module:

  1. Switch off the 12VDC power supply.
  2. Each 0-10V dimmer has a GND (or 0V) connection and an analog in (0-10V). Connect the GND connection of each dimmer to the GND of the Dim Control Module.
  3. Connect one of the 1-8 connectors of the Dim Module to the 0-10V input of the dimmer.
  4. Connect the Circuit breaker switched VAC mains to the external dimmer modules followed by the lighting fixtures (please use a qualified electrician to make those connections). Always switch off your Circuit breakers before making any modifications or making any connections to the dimmers or OpenMotics system.
  5. Power on the 12VDC power supply and check the status of the Modules on the bus (power LEDs on all Modules should light up). When the power LEDs do not light up, immediately switch off the power supply and look for possible causes.
  6. To test Dim Control outputs: the CLI instruction “output on 5” will switch ON output 5, “output on 5 63” will switch ON output 5 at full light capacity, “output on 5 31” will switch ON output 5 at half capacity, “output off 5” will switch OFF output 5.


WARNING

The GND connector is not the same as the Earth or N connection of the mains 110-230VAC! The GND connection is galvanically isolated from the VAC mains. On this Module, only low voltage connections (max 12V) should be made. Incorrect wiring may cause severe injury, fire, broken equipment and even death.

Connecting Led strips

Your can connect normal ledstrips (single color or RGB) and have the possibility to dim your strips and chose your color (when using RGB strips) by using the Openmotics Dim Control.

Important remarks:

  • You CANNOT directly connect Ledstrips to the 0-10V output of the Openmotics Dim Control. The Dim Control cannot drive leds directly and needs a Led dimmer like the DimL3-5-360 or any other led dimmer with an 0-10V input.
  • When buying RGB leds strips, make sure you buy common anode strips if you want to apply the DimL3-5-360
  • When installing ledstrips, it's advised to use protected strips (with IP6x) which are less sensible to break. For bathrooms or outside, it's an absolute must to use ledstrips with at least IP64 protection level.
  • In the market, you'll find 0-10V devices and 1-10V devices. The Openmotics Dim Control is only compatible with 0-10V devices. Some devices in the market exists that supports both standards and those can be used as well.
  • 0-10V (current sourcing - compatible with Openmotics) and 1-10V (current sinking - NOT compatible with Openmotics) are standards but not always used in the correct way by the different vendors so extra care needs to be taken before buying a driver. The example of the below led driver (DimL3-5-360) which is a current sourcing type but still has an indication of 1-10V.

The below examples uses 3 outputs of 1 Dim Control, of course, you can use all 8 outputs for more ledstrips or any other type of dimmers.

Connecting 0-10V Heating Valves

Your OpenMotics system can control up to 24 programmable thermostats. These thermostats will drive heating valves or actuators for PID driven proportional heating control.

The OpenMotics system allows you to connect 0-10V regulated heating Valves as well as any other (24V, 230V etc) Open/Close valves. When the Open/Close valves are used, these are directly connected to an Output (Relay) Module.

When regulated 0-10 Valves are used (Brand Belparts for example), these valves are connected to the Dim Control Module as described below. In the following example the Belparts Alpha-Actuator 4 is used.

Belparts.jpg


To connect Belparts heating valves to the Dim Control Module:

  1. Switch off the 12VDC power supply.
  2. Ask a certified electrician to make the mains connection (110-230VAC) to the 24V power supply
  3. Switch off the 24VAC power supply.
  4. Connect the 0V or ground output of the 24V AC power supply to the GND of the OpenMotics system. This can be done by connecting the GND of the 12V DC output to the GND (or 0V) output of the 24V AC output.
  5. Connect the GND of each Belparts valve (blue cable) to the GND of the system. Only use cable designed for 250mA (or 2W) should be used (at least 0,5mm2).
  6. Connect the 24VAC of each Belparts valve (Black cable) to the 24VAC of the power supply. Only use cable designed for 250mA (or 2W) should be used (at least 0,5mm2).
  7. Connect the 0-10V of each Belparts valve (Red cable) to an output (1-8) of a Dim Control Module.
  8. Power on the 12VDC and 24 VAC power supply and check the status of the Modules on the bus (power LEDs on all Modules should light up). When the power LEDs do not light up, immediately switch off the power supply and look for possible causes.

Notes:

  • When the valves in the example above are powered on a self-test is performed. During this test (10 minutes) the valve will completely open and close so during that time the valves cannot be used.
  • The orange status led will only flicker when communication is happening between the module and the Gateway. In normal circumstances, the status led will not flicker except when a port will change state or when the dimmer output value is changed.
  • If you've some questions regarding which type of dimmer, heating valve/actuator or switch to use, please see the Additional Material page.


WARNING

The GND connector is not the same as the Earth or N connection of the mains 110-230VAC! The GND connection is galvanically isolated from the VAC mains. On this Module, only low voltage connections (max 12V) should be made. Incorrect wiring may cause severe injury, fire, broken equipment and even death.

Connecting Daikin heating/cooling

Openmotics also supports the integration of Daikin equipment in combination (or without) other heating/cooling installations. For more details, please see Daikin Setup page.

Connecting the Temperature Module

The Temperature Module adds environmental parameters to your OpenMotics system to control your heating and/or perform additional special functions (control stores when sun is shining, switch on lights when movement is detected, switch on fan when humidity is too high etc.). The system has been designed to handle sensors connected with very long cables (up to 200 meters). Each Temperature Module can connect up to 8 different sensors and each OpenMotics system can handle up to 4 temperature modules, thus providing up to 32 sensors.

Multiple types of sensors exist:

  • Temperature only
  • Temperature & light measurement (AD converter)
  • Temperature & humidity
  • Temperature, humidity and light (AD converter)


Temperature.jpg

To connect sensors to your Temperature Module:

  1. Switch off the 12VDC power supply.
  2. Connect the GND connector of the Module to the GND connector of each sensor as shown on Figure 10 below.
  3. Connect the 5V out connector to the +5V connector of each sensor.
  4. Connect the CLOCK connector to the CLK input of each sensor. Please note that the CLOCK wires of multiple Temperature Modules can NOT be mixed. Every Temperature Module must have its dedicated clock line for his connected sensors.
  5. Connect each sensor SDA connector with 1 individual Module input (’1-8').
  6. Power on the 12VDC power supply and check the status of the Modules on the bus (power LEDs on all Modules should light up). When the power LEDs do not light up, immediately switch off the power supply and look for possible causes.

Notes:

  • The sensors only work on the protected and current limited 5V provided by the Temperature Module. The temperature module can switch the 5V and thus reset the sensors when this would be required (sensor blocked for example). DO NOT connect them to any other source as this can destroy them !!!
  • When a sensor is connected, the led on the temperature module of that sensor will light up (when the system is not in power safe mode). It will however take a few minutes before the Master will see the correct environmental values, in the mean time, the Master will show the sensor as "Not Connected".
  • Once a Temperature module has been added through the portal (or via maintenance mode), the orange status led will flicker every few seconds to indicate that communication is working. This is normal behavior.


To built-in a sensor, different methods can be used. What often is applied by our customers is using the casing of a buzzer (example Btcino 0038/005045). Those buzzers are low cost and we just remove the buzzer and insert the sensor instead. The pictures below shows an implementation which is easy and straight forward. As a side note: Please use some silicon to cover the holes at the backside of the buzzer module to prevent wind and cold in your wall that can influence the temperature sensor measurement.

Some other examples:

Switch10.jpeg Switch11.jpeg Switch12.jpeg

Connecting the Energy (Power) Module

The Power module has been replaced by the Energy module and is no longer available for purchase. While the old Power module only allowed single phase and up to 8 current sensors to be connected, the new Energy module allows 3 phase and up to 12 current sensors. The front panel display has been removed and the module width increased to 6 (was 5).

Bus+power.jpg

The Power modules must be connected to BUS2 of the Gateway module and not BUS1, see the wiring the bus chapter.

  1. Power off the 12VDC power supply and all 110-230VAC circuits prior to performing any work!
  2. Many voltage net configurations exist (single phase, 3 phase, WYE, delta, etc.). Please confirm which applies to your installation prior to installation
  3. Follow the instructions on the Energy Module Installation page.

Module front panel LED functionality

To understand the functionality of the different LEDs on the OpenMotics modules, please see the below links:

Remote controls and wall screens

Openmotics also supports RTI and has created a 2-way driver on request of our customers. For more information, please see the RTI page.

The disadvantage of the RTI system is that it's not opensource and installer centric so if you know good quality 2-way remotes and wall screens, please let us know on support@openmotics.com.
